Abstract

Die Erfindung betrifft eine Lüftersteuerung (LS) und ein Verfahren zur Einstellung der Drehzahl eines Lüfters. Die Lüftersteuerung (LS) ist dazu eingerichtet den Lüfter in einem ersten Temperaturbereich einer Lüfterkennlinie auf einer konstanten Drehzahl zu halten. Die Lüftersteuerung (LS) weist einen digitalen Vergleicher (DV) zum Vergleich einer erfassten Ist-Drehzahl mit einer vorgegebenen Minimal-Soll-Drehzahl in dem ersten Temperaturbereich auf.

The invention relates to a fan control (LS) and a method for adjusting the speed of a fan. The fan control (LS) is designed to keep the fan in a first temperature range of a fan characteristic at a constant speed. The fan control (LS) has a digital comparator (DV) for comparing a detected actual speed with a predetermined minimum target speed in the first temperature range.
